For many people “solidarity” has become a meaningless word used in slogans – too often used without leading to any economic consequences. We show in this paper conditions under which solidarity can be a powerful instrument. In a solidary action, an individual in a group contributes to a series of actions that aims for a reallocation of scarce resources. The willingness to contribute is mainly i...

We discuss UV/IR mixing effects in non-supersymmetric noncommutative U(N) gauge theories. We show that the singular (nonplanar) terms in the 2and 3-point functions, namely the poles and the logarithms, can be obtained from a manifestly gauge invariant effective action. The action, which involves open Wilson line operators, can be derived from closed strings exchange between two stacks of Dbrane...

In this note we derive the low-energy effective action of type IIB theory compactified on half-flat manifolds and we show that this precisely coincides with the low-energy effective action of type IIA theory compactified on a Calabi–Yau manifold in the presence of NS three-form fluxes. We provide in this way a further check of the recently formulated conjecture that half-flat manifolds appear a...

This article addresses two topics. We provide an overview of the National Institutes of Health Mouse Metabolic Phenotyping Center (MMPC) Program. We then discuss some observations we have made during the first eight years of the Vanderbilt MMPC regarding common phenotyping practices. We include specific recommendations to improve phenotyping practices for tests of glucose tolerance and insulin ...

Reciprocity is a core institution that allows diverse individuals to engage in collective action. Collective action is essential to meet the goals of sustainable development. The twin goals of sustainable development are to protect the well-being of individuals and ecosystems in ways that are socially just. These twin goals constitute the win-win paradigm. However, tradeoffs in socialecological...

6-Phosphogluconate dehydrogenase from Candida utilis catalyzes the oxidative decarboxylation of 2-deoxy-6-phosphogluconate. The 3-keto-2-deoxy-6-phosphogluconate, an intermediate of the reaction, is reduced to 2-deoxy-6-phosphogluconate and decarboxylated to I-deoxyribulose 5-phosphate when incubated with the enzyme and TPNH. The decarboxylation process does not occur in the absence of the redu...

Traditionally, communication has been defined as the intentional exchange of symbolic information between individuals. In contrast, the mirror system provides a basis for nonsymbolic and nonintentional information exchange between individuals. We believe that understanding the role of the mirror system in joint action has the potential to serve as a bridge between these two domains. The present...

this study investigates the effects of  macroeconomic variables and their role in development of foreign exchange market. the foreign exchange market is the mechanism by which a person of firm transfers purchasing power form one country to another, obtains or provides credit for international trade transactions, and minimizes exposure to foreign exchange risk. the foreign exchange transaction i...
